Hi,
There are some 0870 numbers where O2 users can take advantage of to dial back to HK via the free minutes.

Unfortunately, Orange and T-mobile are charging calls to all 07744 numbers, I strongly suggest NOT to use any 07744 access numbers that were free before.
You will be better off have a BT landline. 1) It is cheaper to call from HK. 2) It is cheaper to call from UK via company such as top-tel

BT Landline is 10.50 pounds per month. Usually ready within 2 weeks for a new line. If there is an existing line, it will take 5 working days to re-enable the line.
Hope this helps.
